I also tried using JZZ().or(...) which has the same behavior.

I am not expecting JZZ to work on WSL2 (or any Docker container running on top of a Windows host for that matter)--but it would be nice to have it able to catch the errors rather than let it crash catastrophically.

This is now also failing on Ubuntu and WSL1

Likely due to the fact that there is no snd device

Interesting problem...
Apparently, there is no /dev/snd/seq on Windows.
I wonder if any MIDI application works on WSL at all...

lhl2617 commented

On ubuntu it may fail if the system doesn't have any sound devices: https://github.com/lhl2617/jzz-wsl2-repro/runs/2583738892?check_suite_focus=true

I doubt so--it took me a whole day to set up even simple audio playback via a Pulse server. Though, I think more importantly the call to JZZ() should fail gracefully

jazz-soft commented

That makes sense. Hopefully it can be fixed on the jazz-midi side...
Thanks a lot for bringing it up!

Please update jazz-midi to v1.7.5 - it should work now (I hope)...

Still getting the same result after running npm i jazz-midi@1.7.5

$ npm run start

> jzz-testing@1.0.0 start /home/$USER/experimental/jzz
> node index.js

Pushed to repo. GitHub actions is currently dead, but we should be able to see results later...

Yes, I keep the ALSA warning, but it should not throw anymore.

Ah my bad! Yes it does work now :) Thanks so much!

PS--would be great if you could update and re-release the JZZ/jzz-midi-smf etc. packages with "jazz-midi": "^1.7.5"
